Mark busied himself with setting up the tent, his hands moving with practiced ease. He hammered the stakes into the ground, securing the canvas to withstand any overnight winds. John, meanwhile, was unloading the car, carefully placing their supplies on the table.

“Hey, Mark” John called out, breaking the silence. “I must say, last week when you asked me to go camping, I thought you were joking.”

Mark looked up from his task, a grin spreading across his face. “Why would I joke about something like this? You know how much I love the outdoors.”

John chuckled, shaking his head. “Yeah, but it’s been a long time since our last camping trip, you know.”

The lake shimmered under the fading light, its surface reflecting the vibrant colors of the sunset. Birds chirped their evening songs, and a gentle breeze rustled through the trees.

“Mark, come here!”
“There’s like, a fresh tire track going straight into the water over there.”

Mark didn’t look up. “Yeah, probably some dudes messing around.”

John wasn’t convinced. “The lake looks pretty deep right there. Are you sure this is safe?”

Mark reached the spot John had pointed out. He crouched down, examining the ground. “You’re right, John” he said finally, his voice low “those are fresh tracks. Makes you wonder what happened here, doesn’t it? I can tell there was an accident here earlier!”

John responds “Accident? How do you know that?”

The question hung in the air, heavy and unwelcome. Before John could get another word out, Mark made a swift, silent move. A metal baseball bat hidden behind his back, hit the back of John’s head with a sickening thud. The world spun, the lake turning into a swirling vortex, his vision blurs before fading to black.

Mark knelt beside him, the bat held loosely in his hand. His face showed a mix of rage and desperation as he leaned close to John’s ear. “Because, John” he said, a twisted smile playing on his lips “I’m the one who caused it.”

The smile faltered for a moment. “You should never have told my wife about Maya” he rasped, his voice tight with barely contained rage. “I should never have told you about her in the first place. You were my best friend! I trusted you!”

The weight of Mark’s words settled on him, heavy and suffocating. It was Maya, the woman Mark had confessed to him: another affair. The woman Mark had sworn him to secrecy about just before their wedding. John, filled with guilt and remorse, had broken that promise, blurting out the truth to Mark’s wife in a misguided attempt to ease his own conscience. Never did he imagine the devastation his confession would unleash, a consequence far worse than anything he could have ever imagined.

“Don’t worry, John” Mark continued. “It’ll all look like a tragic accident.” He cast a cold glance at John’s unconscious body. Mark, fueled by a week of meticulous planning and a heart consumed by vengeance, knelt beside John. The carefully placed tire tracks, the staged accident scene, all part of the chilling performance.

With a little bit of effort, Mark dragged John’s unconscious body towards their parked car and sat him into the driver seat. A monstrous grin stretching across his face. With a final, lingering look at his former friend, Mark pushed the car towards the lake. The metal crunched as the vehicle plunged into the inky water, disappearing beneath the silent surface.

PS: I really want to disclose my (former) best friend’s affair to his fiancée (I heard they’re getting married), but I’m afraid bro might take me to a nearby body of water and kill me.
